Aluminium oxide is responsible for resistance of metallic aluminium to weathering. Metallic aluminium is incredibly reactive with atmospheric oxygen, and a thin passivation layer of alumina (four nm thickness) forms in about a hundred picoseconds on any exposed aluminium surface area.[5] This layer shields the metallic from additional oxidation.
